Statistical Area 1 2021 (Centroid Inside)
This dataset was first added to Stats NZ Geographic Data Service on 07 Dec 2020.
This dataset contains the inside centroid point layer for the annually released statistical area 1 (SA1) boundaries as at 1 January 2021. The "inside" centroid is a point which always falls inside each SA1 polygon as this is often desirable. The placement of the point is typically in the widest part of the polygon. The algorithms used are proprietary to ESRI and are related to label placement. Note that the "inside" centroid is NOT always the same as the center of gravity ("true" centroid) of the polygon as in some situations the true centroid may fall outside the SA1 geometry. The dataset contains the EASTING and NORTHING attributes of the centroid point in NZGD2000 New Zealand Transverse Mercator (EPSG:2193) and LATITUDE and LONGITUDE of the centroid point in decimal degrees in WGS1984 (EPSG:4326) projection.

Statistical Area 1 2021 (Centroid True)
This dataset contains the true centroid point layer for the annually released statistical area 1 (SA1) boundaries as at 1 January 2021. The "true" centroid is the centre of mass of that polygon, such that if some flat substance of uniform thickness and density were cut into the shape of that polygon, then that object would balance at the centroid. The centroid is a useful way of summarizing the location of a set of polygons as points, particularly when used for comparative analysis. Note that the centroid could potentially fall outside the SA1 polygon, depending on the shape of the polygon.The dataset contains the EASTING and NORTHING attributes of the centroid point in NZGD2000 New Zealand Transverse Mercator (EPSG:2193) and LATITUDE and LONGITUDE of the centroid point in decimal degrees in WGS1984 (EPSG:4326) projection.
Statistical Area 1 2021 (generalised)
This dataset is the definitive set of annually released statistical area 1 (SA1) boundaries for 2021 as defined by Stats NZ. This version contains 29,910 SA1 categories.
SA1s were introduced as part of the Statistical Standard for Geographic Areas 2018 (SSGA18) which replaced the New Zealand Standard Areas Classification (NZSAC92). SA1 is a new output geography that allows the release of more detailed information about population characteristics than is available at the meshblock level.
Built by joining meshblocks, SA1s have an ideal size range of 100–200 residents, and a maximum population of about 500. This is to minimise suppression of population data in multivariate statistics tables. SA1s either define or aggregate to define SA2s, urban rural areas, territorial authorities, and regional councils. Some SA1s that contain apartment blocks, retirement villages, and large non-residential facilities have more than 500 residents.
Digital boundary data became freely available on 1 July 2007.
The SA1 classification can also be downloaded from the Stats NZ classification and concordance tool Ariā.

Statistical Area 1 2021 Clipped (generalised)
This dataset contains the annually released statistical area 1 (SA1) boundaries for 2021, as defined by Stats NZ, clipped to the coastline. This clipped version has been created for map creation/cartographic purposes and so does not fully represent the official full extent boundaries. This version contains 29,695 SA1 categories.
Meshblock 2021 (Centroid True)
This dataset contains the true centroid point layer for the annually released meshblock boundaries as at 1 January 2021. The "true" centroid is the centre of mass of that polygon, such that if some flat substance of uniform thickness and density were cut into the shape of that polygon, then that object would balance at the centroid.

Meshblock 2021 Clipped (generalised)
This dataset is the definitive set of annually released meshblock boundaries for 2021 as defined by Stats NZ. This version contains 53,598 meshblocks, clipped to the coastline. This clipped version has been created for map creation/cartographic purposes and so does not fully represent the official full extent boundaries.
Stats NZ maintains an annual meshblock geography for collecting and producing statistical data. This allows data to be compared over time. A meshblock is the smallest geographic unit for which statistical data is collected and processed by Stats NZ. A meshblock is defined by a geographic area, which can vary in size from part of a city block to a large area of rural land. Each meshblock borders on another to form a network covering all of New Zealand, including coasts and inlets and extending out to the 200-mile economic zone. Meshblocks are added together to build up larger geographic areas such as statistical area 1 (SA1), statistical area 2 (SA2), and urban rural. They are also used to define electoral districts, territorial authorities, and regional councils.
The following 16 meshblocks are outside the 12 mile limit and are not held in digitised form: 0016901, 0016902, 1588000, 3166401, 3166402, 3166600, 3166710, 3166711, 3195000, 3196001, 3196002, 3196003, 3196004, 3196005, 3196006, 3196007.
The meshblock classification can also be downloaded from the Stats NZ classification and concordance tool Ariā.
Meshblock 2021 (generalised)

This dataset is the definitive set of annually released meshblock boundaries for 2021 as defined by Stats NZ. This version contains 53,598 meshblocks.
Constituency 2021 Clipped (generalised)
This dataset contains the annually released regional council constituency boundaries for 2021, as defined by the regional councils and/or Local Government Commission and maintained by Stats NZ (the custodian), clipped to the coastline. This clipped version has been created for map creation/cartographic purposes and so does not fully represent the official full extent boundaries. This version contains 64 categories.
Constituencies are established under the Local Electoral Act 2001 and result from the division of a region for electoral purposes.If a regional council decides to have a Māori constituency, the constituencies within the council are known as general constituencies and Māori constituencies.Constituencies are divisions of regional council areas. They are defined at meshblock level, and do not coincide with the statistical area 1 (SA1) geography or the statistical area 2 (SA2) geography. They are created, based on population, to be the voting areas within councils. Constituencies are required to reflect communities of interest. Their boundaries, so far as is practicable, coincide with those of territorial authorities or wards.
Names are provided with and without tohutō/macrons. The name field without macrons is suffixed 'ascii'.
Regional Council 2021 Clipped (generalised)

The regional council is the top tier of local government in New Zealand. There are 16 regional councils in New Zealand (defined by Part 1 of Schedule 2 of the Local Government Act 2002). Eleven are governed by an elected regional council, while five are governed by territorial authorities (the second tier of local government), who also perform the functions of a regional council and are known as unitary authorities.
Auckland Council unitary authority was formed in 2010, under the Local Government (Tamaki Makarau Reorganisation) Act 2009, replacing the Auckland Regional Council and seven territorial authorities.The seaward boundary of any coastal regional council is the twelve-mile New Zealand territorial limit. Regional councils are defined at meshblock and statistical area 2
